Abstract

Several different potassium channels modulate the activity of sleep-promoting neurons in the Drosophila brain, but the regulation of these channels is not completely understood. A recent study (Kempf et al., Nature, 2019) found that one of the potassium channel subunits, Hyperkinetic, alters the firing properties of sleep-promoting neurons in response to NADPH oxidation. These findings are the first to link cellular redox state and mitochondrial metabolism directly to sleep.
